Answer 1

Longer handle for water pump is preferred because, longer the handle less will be the force required.

This follows the principle of moment of force, which is the product of force and the perpendicular distance of line of action of force from the axis of rotation

Hence, more the length of the handle less will be the effort required

Answer 2

Hola Mate!!!!!

Answer :-

The long handle of a waterhandpump have more area so it is easy to move up down so that the chain pull out the water .

As due to long handle we have to apply less pressure which saves our energy.

It's long handle work as a lever or pulley.
